Caps
We are gonna shoot for between 4000-5000uF by using two of the following
- Vendor - Digikey

- datasheet
Current Limit
To try to save our silicon, we have decided to try to limit the current using a sense resistor, a comparator, and some logic.
Current Sense Resistor
- Vendor - Digikey
- Vendor Part Number - FCSL90R010FERCT-ND
- Manufacturer - Ohmite
- Manufacturer Part Number - FCSL90R010FER
- Cost - $1.20
- digikey
- datasheet
Comparator
- Vendor - Digikey
- Vendor Part Number - MCP6541RT-E/OTCT-ND
- Manufacturer - Microchip
- Manufacturer Part Number - MCP6541R
- Cost - $0.43
- digikey
- datasheet
Isolation
We need to isolate the voltage sense, and the kick signals. This gives
- Sense (SPI)
- CLK - IN
- CS - IN
- Dout - OUT
- Trigger
- Chip - IN
- Kick - IN
So we need 4/1 in/out isolation
Isolator
- Vendor - Mouser
- Vendor Part Number - 634-SI8451AA-A-IS1
- Manufacturer - Si Labs
- Manufacturer Part Number - SI8451AA-A-IS1
- Cost - $2.43
- mouser
- datasheet
Power Supply
The DC/DC converter needs to power the
- ADC - 5V 500uA
- Isolation - 5V 6mA
- Comparator - 5V 5mA (ballpark)
- Comparator Logic - 5V 5mA (7400 series logic, probably almost nothing)
- IGBT driver - 12V 10mA (be sure to bypass Vbat with 4.7uF ceramic, 47uF tantalum)
So lets shoot for around 5V 50mA LDO and around 12V 100mA DC/DC converter
Isolated DC/DC Converter
- Vendor - Digikey
- Vendor Part Number - 445-2473-ND
- Manufacturer - TDK-Lambda
- Manufacturer Part Number - CC3-1212SF-E
- Cost - $11.37
